ADJUSTABLE CLUTCH BRAKE.'

Appiieatifm'ined-september23;192e. semi No. 137,268.

This invention relates to motion transmitting mechanism such "as are used in automobiles and has for its object a lparticularly simple, eiii'cient,dui"able and'adjustable brake forietarding the rotation ofthe driven inember of the' clutc'l'i when the clutch is released.

The invention consistsin the novel features and i'n the' combinations and constructions hereinafter set forth andclaiined.l

Vi0 In describing this invention, reference is had to the aoconip'anyi'ngy drawing in which like characters designate `corresponding parts in all the views.- y Y Y j Figure 1 is a side elevation, partly inv section and partly broken away. of the transmission mechanism embodying my invention. Figure 2 is a fragmentary detail View thereof. f j' Figure 3 is an elevation of the bearing cap ao-fand c'ontguousipar'ts; p

. Figure 4 is a detail viewof the' lock for the bearing cap. j.

This motion' tra'nsinittino" mechanismv coinprises generally'ja clutch' olajny-suitable Vconstruction includin g1 the usua'l shaft and throwout collar slidable axiallyof the shaft, a sup` port for thejsli'a'ft' in the' rear of the throw# out collar, thisfsupport' being usually the front ing in said wall in which the shaft is journalled andmeans associated with said bear! ing and adjustable axiallyof the shaft in the rear of the throw-outcolla'r, said means being connected tothe bearing to be adjustable axially thereof relatively to thev shaft and 'having 'afrbrakinfg` element opposed to the rear face of the throw-out collar whereby when the throw-'Out collar is actuated to release the clutch, rotation thereof is retarded 40 by said brake' element and whereby it caribe adjusted: to take up wear of thebrake element.v The clutch may be'of any suitable f form, size and construction and as many forms ofvthese clutches are well known and understood, detail construction is thought to be unnecessary.l

All of these clutchesinclude a driven shaft as 1 which is usually the stemof afstem gear ENRY Wswnrin or vsizia'acusn, NEW Yoii'i, Assiduo-agro BROWN-Lien GEAR colit- 2 of the usualtransinission gearing, the shaft f or stem ofthe gearxbeing jou'rnalled in an anti-friction bearing 3' mounted in the front wall 4 of the transmission gear-case' which front'wall forms the support for the rearY end of the shaft as will be understood by those Skilled in' the art. y,

The clutch also includes a throw-out collar 5 slidable 0nl the shaft l ,and rotatable theifewith' as it isp'arto'f the driven element ofthe j clutch. This throw-out Collar hfas' athrowvout bearing 6 which cOacts wi'ththeyokeop- .e'rated' by the usual Clutch pedal of an auto-. rmobile',4 all of which willbe those Vs'kil'l'edi'n`-the art.` j A Y j The bearing 3' is here shown las anantifriction bearing including outer and inner understood by rings 4' and 8 and antiifrietion bearings as Y balls between the rii'igs.` The outer` ring? is mounted' in a cup or casingrQ secured in an opening in the wall 4 ofthe transmission gearcase and the inner ring 8 mounted on an enlargement l0 of: the shaft 1. The inner ring is held' from axial displacement by a nut The bearing fui-ther includes a-'be'aring' .cap

A13se`cured tothel casing 9 or jthey wall 4 by V11 threading on .the eiilargeii'ient 10 rgfii'-nst the ring 8 or an interposed lock washer 12. wallfof the transmission gear casi'ngg ai bearadjustable axially relatively vto the outer body l portion, this central portion or hub being 'opposed to the throw-out collar 5 and also engaging the periphery of the sha-ft 1.1' Abrah-v ing 'element or disk 15 is interposed between the collar 5' and this inner. central part or hub 1G. The inner' central part or hub is here sh'ownas a collar which threads into the bearing cap 13 and which is provided with an oi'lfeeding or retaining groovel? around the shaft 1.. l/Vhenthe th'roweout collar 5' is moved :rearwardlyto release the-clutch',` it

engages the braking element or'disl; 15 and 'pressos'it against the part or collar 16 thus retarding the rotation of the driven member fnally threaded'barr-el 2O which threads into la radial passage in the outer body of the ternal shoulder inthe barrel. The plunger 1 at its vouter end extendsoutside of the barrel and is provided witha diametrically extending pin 21, and the outer end of the barrel is also formed witha coinpleinental slot 223.

A,The pin normally lies in the slot.

To release the plunger from the collar 16 when it is desired to Iturn the collar to take up forv wear of thebr'ake Ydisk 15 the` plungei' is moved axially until the pin 21 is out of the slot 23 and then the plunger isturne'd to, bring the pin out of alineiiient with the Slot In operation, to adjust the collar 16 to take s up `for wear of the brake disk 15, the opera- .tor after removing vthe handV hole cover in the clutch casing inserts a screw driver `or Vother tool and engages the pinv 22to shift it ,axially and give it a partial tarn to hold the plunger 18 in its inoperative position'. Y The operator can then with a screwl driver turn the collar 16 as much as desired and then lrelease .the plunger 18 by turning'it so that the pin 22 can enter the slot23.

Ths invention is particularly advantageous in that it provides g an exceptionally simple construction by which-the clutch bralre can be adjusted for wear.
